At the age of 15 you know what your actions do and that you'll have to answer for them.
Unfortunately, they will goto jail and come out bigger assholes.
Why did that dude shoot him if he was being cooperative
Three lives ruined for less than 100$ I imagine.

"They are only 15 and capable of turning their lives around". Statements such as those make my blood pressure rise. I bet their parents will be telling all that will listen that "They are good boys that just fell in with the wrong crowd".
If at 15 they don't know that it's not normal to rob and kill people then society no longer has a use for them.

FUCK all that noise.
I say we bring back the chair for those fucking degenerates!
Crank that motherfucker up to 100.
